' 1928.l Serial The present invention is a division of application for patent Ifiled vJ une 16th 1927,

Serial #199,314, upon method and apparatus for'V -making and method of applying asphalt plates. p 'f The ypresent invention, in its broad aspect, has to; do with improvements iny means and methods of scouring and polishing` bitumastic, asphaltic, asphalticgranito, and the likeyplates' or'use as floor, aisle, wall or other surface coverings. Asphaltic or bitumastic, or asphaltic-granito plates, such as areoperated upon b 'this present appa#` ratus may be made a ter the method described in'PatentLT'TI-L6435O59, granted Sepf ytember 20th 1927, and when'applied form a desirable, wear resisting and durable surface which is vfree from dust, and which is both moisture and Weather proof and of pleasing and artistic aspectand appearance. In or-Y dinary practice `the materials forming the asphalticor bitumastic mass from which the plates are made are preferably compounded according totwo formulas; the first, involvin'g the :use of ground-asphalt rock ,and 15 to -20 per cent of bitumen; andthe second, a mixtureof asphalt mastic (a commercial product) and a per cent of bitumen and sand to attain the desired consistency.v When it is desiredto form asphaltic-granito plates 'from 15 to 42() per cent very fine v(about 00' degrees comm'inution) vmarble chips (without dust) are added to the massf vIt, is1 especially l*in the forming and scouring and polishing of asphaltic-granito plates that the lpresentvinventionis directed.l `The scouring machine comprises a table, a reciprocating element and aballast element; and in operation, vasphaltic-granito vplates areA transported (after being cut) to the scouring machine and' a layervof plates laid bottom side or black vvside up (the-top'side bearing the addition of4 marble chips); another 'layer is superposed on the vfirst 'layer withA ther-bottom or black side dow-n, the ballast n elements ka-refthenV lowered by a suitable winch `,and-are fastened by a= punching instrument -to preventshiting ksandis now spread onthe yassembly and the whole is sprinkled f withfwater whereupon the .device .laid upon a Hoor or the like.

ly definedthefollowing; first,-the scouring table is*` formed largely-of channel iron and plate metal. which isv obtainable on thev open market rand therefore facilitates' .thenianu-Y f facture ofthe machine; second, novel means are provided for blocking up and ad'jllStilg vthe'plateson the table; third, the ballasting device is' formed `inV sections which Vmaybe taken-down yand the like, and', onrth,",tlie 1' scouring device is simple in' construction, Y. and positiveand practical in "operation,` i With these and other objects in'view the invention consists` in the novel steps and combinations y'off steps vcoinstituting` the method, and in the Ynovel ,details of construction and arrangements ofv parts .con-V stitutingithe apparatus, as will' be more fully ldisclosed -hereinafter, pointed out in the claims.

Figured-is a;de`ta'il view ofthetplate l adjusting a-ndblockingfdevice, and

particularly Figure 6 is a detail View of a modified form of plate adjusting and blocking device.

In the drawings, like characters of reference are used throughout the several views to designate like or similar p arts.

In forming asphaltic-granito plates mar-l ble chips are sprinkled over the tops thereof and it is necessary togrind or scour the same to form an even and pleasing surface. Other plates besides asphaltic-granito plates are adapted to be operated upon by the device, but these are used for the` sake of 1llustration, and especially to bring out the application of the method.

The device comprises a relatively masslve base (1) on `which the stringers (channeliron) (2) are bolted as at Upon the Stringer-s is mounted the table (4) which 1s transversely reinforced as at The operative, or movable element, of the machine is a rectangular plate metal form or scouring member (6), one end of which is provided with a coupling (7) for the end of the pitman or crank (8) of a power element (not shown) which is designed to reciprocate the member (6) at about 60 R. P. M. of the power element when in action. The form or scouring member (6) is slidably mounted as at (9) on rods (10) carried by su ports (11) on the bed, fioor or table (4). The asphaltic-granito plates, designated (12) and (13), are placed on the table (4). Plate 12 is properly blocked against shifting by the clamp shown in Figures 5 and 6, and which comprises a wooden block (14), a follower (15) and a screw actuating means (16) engaging the frame of the floor and having a hand wheel (17). The follower (15) works on the smooth shank (18) of the screw (19) which carries the hand-wheel (17), and a washer (20) is preferably placed between the hand wheel and follower. The block engaging, and over-bent portion (21) of the follower works in a recess (22) in the edge of the table, and sets below the stock so as to be out of the way, although it is above the top surface of the table. An alternate form is shown in Figure 6 wherein the follower (23) is arranged on channel member (24) and has a hand wheel (25) to adjust the block (26) in this case the follower is above the block (26) but outside the periphery of the table, and the. channel member is recessed as at (27) to allow movement of the follower toward the table. In practice the layerv of plates (12) are placed bottom or black side upon the table, and clamped immovably in place by the followers shown in Figures 'and 6, thereupon another layer (13) is superposed thereon placed bottom or black side down. This latter layer is free to slide on the layer (12), and sand is sprinkled or placed `between the two `layers. The ballast element is then lowered upon the layer of plates 13. The ballast element fits between the side and end rails of the rectangular scouring member 6 and comprises a plurality of plates (28) attached each to supporting frame members (29) .of L-iron, spacers (30) being used, and chains (31) connect the frame members to a winch (not shown) for raising and lowering the same. After the sand has been placed between the layers of plates (12) and (13) they are sprinkled with water so that the sand is wet. The ballast having been applied and the scouring frame set in motion, the layer (13) is rubbed across the layer (12) and the operation is kept up until the proper finish is obtained.

It is obvious that those skilled in the art .may vary the details of construction as well as the arrangements of parts without departing from the spirit of the invention, and

therefore it is not desired to be limited to the foregoing disclosure except as may be required by the claims.

What is claimed is y 1. In an apparatus for scouring plates, a ballasting member for the plates comprising angle iron frame members, and plurality of ballasting plates each connected to the frame members, and attaching means engaging the frame members for lifting the ballasting assembly.

2. Apparatus for scouring asphaltic plates comprising a base, relatively parallel stringers fixed to the base, a reinforced table member fixed upon the stringers, a plurality of supportsv carried by the sides of the table, a frame slidably mounted in the support above the table, means including a follower and blocks bearing against a layer of plates on the table for holding the plates in place thereon beneath the frame, a ballasting element in the sliding frame and composed of a plurality of connected plates for engaging a layer of plates disposed on the first layer,and means for reciprocating the frame to cause the latter plates to move on the fixed layer of plates thereby to scour the plates.

3. Apparatus for scouring asphaltic plates comprising a base, relatively parallel stringers fixed to the base, a reinforced tablev member fixed upon the stringers, a plural-4 ity of supports carried about the sides of the table, rods engaging the supports, and carried by a frame for slidable movement, whereby said frame may be reciprocated back and forth over the table, means including a screw follower and blocks bearing against the layer of plates on the table for holding the plates in place thereon be-D neath the frame, a ballasting element in the sliding frame end comprising plates and means fork attaching said plates together to form a unit, said ballasting element bearing against a layer of plates disposed on` the first layer of plates and means for reciprocating the frame to slide the top layer over the lowerl layer of plates thereby to scour the plates.

In testimony whereof, I ,affix my signature hereunto.
